IMPROVEMENT IN APPARATUS FOR BENDI'NG TlRS.

Specification forming part of Letters Patent No. 34,506, dated February25, 1862.

To all whom it may concern:

A Be it known that I, GABRIEL FAENER, of Marion, in the county ofFranklin and State of Pennsylvania, have invented a new and usefulImprovement in Machines for Bending Tires; and I do hereby declare thatthe following is a full and exact description thereof, referencebeinghad to the accompanying drawings, and to the let-ters of referencemarked thereon.

The common method of adjusting the rollers of tire-benders by means oftwo screwsone at each end of such rollers-is objectionable, because itis difficult with such arrangement to adjust the rollers so as to bendthe tire without twisting the same. To remedy this defectis the chiefobj ect of my invention. This obj ect is accomplished by arranging oneof the rollers on a sliding frame or gate, and by moving such gate androller by means of a single screw which acts equally on both ends of therollers. My improved machine is also very simple, compact, cheap,efficient, and durable.

In the accompanying drawings, Figure I is a side view of my machine.Fig. 2 is an end Fig. 3 is a top view.

Into the simple but strong frame A are placed two rollersF and F One ofthese rollers F is provided with a cog-wheel L and a pinion E, thelatter being furnished with a crank. Between these two rollers F F Iisplaced a third roller H, supported by a sliding frame D, upon which isplaced a scale, as seen in Fig. 1. This frameand its roller may beelevated and depressed at pleasure by means of a screw d, passingthrough the bar .I of frame D. Thus the relative positions of the threerollers are changed so as to bend tire to it wheels of differentdiameters.

The scale seen in Fig. l and the index-bar c enable the operator toregulate the curve of the tire, so as to lit any wheel, by bringing theproper figures on the scale to the top of bar c.

In constructing my machine I prefer to use iron, except for the sides A,(of the frame,) which are made of planks, say four inches in thickness.

I am aware that a scale is not vnew in tirebenders, and that rollers areoften made adjustable; but I believe my construction and arrangement oftire-benders are in many respects an improvement upon similar machinesheretofore known; but I confine my claims to the most important featuresabove described.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent of the United States, is-

The combination of the middle roller H, the sliding frame, the guides,and central screw d with the scale, Fig. 'l, and index-bar c, or itsequivalent, substantially as specified.

In testimony whereof I hereunto set my hand.

GABRIEL FARNER.
